Procurement Notes
Verify the specific suffix 'LF-Z' against the manufacturer's latest datasheet to confirm lead-free status and RoHS compliance. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the component marking code with official documentation to prevent counterfeit risks during sourcing.
Selection Notes
Select this component when designing systems with 2 to 3 series lithium-ion batteries requiring up to 2A charging current. Ensure the input power source can provide sufficient voltage within the 24V limit. Verify that the thermal design accommodates the 28-QFN package dissipation characteristics at the expected operating ambient temperatures.
Part Context
This part belongs to the MP2619 family of battery chargers from Monolithic Power Systems. It is distinct from single-cell or lower-voltage variants in the same product line. The EV suffix typically denotes an evaluation board version, but the core IC functionality aligns with the standard MP2619 specifications for multi-cell applications.
Replacement Considerations
MP2619EV-LF-P is listed as a parameter-equivalent alternative by distributors.
